As part of the program management team, MBP provided assistance to VDOT with independent review and evaluation of contractual documents prior to VDOT executing the comprehensive agreement with the design-build team. Analysis included cost estimating, review of technical requirements, quality assurance program requirements, and other contractual language. During the design and construction phases, MBP provided review of submittals and development of the independent assurance and independent verification programs for oversight of the concessionaire’s quality assurance program. MBP also provided support to the program management team in areas of on-site construction management and inspection, project controls, budget management, and CPM schedule review and analysis. This project consisted of a new two-lane, immersed tube tunnel under the Elizabeth River parallel to the existing Midtown Tunnel, maintenance and safety improvements to the existing Midtown Tunnel, minor modifications to the interchange at Brambleton Avenue/Hampton Boulevard in Norfolk, maintenance and safety improvements to the existing Downtown Tunnel, and extending the MLK Expressway from London Boulevard to Interstate 264 with an interchange at High Street. This design-build, public-private partnership project includes the requirement for the concessionaire to design, build, maintain, and operate the facilities for 58 years.
